Title: Packing structure of powdered food
Inventor: KITAGAWA TATSUO
IPC: B65D81/26
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent modification due to oxidation of powdered foods which are housed in a small bag by giving air permeability to the small bag and forming an outer bag without air permeability, in a packing structure which is put in the outer bag which houses a plurality of small bags for housing powdered foods together with the small bags and which is sealing an oxygen scavenger. SOLUTION: A small bag 1 for housing powdered foods such as powdered tea, powdered soy sauce, and sugar has air permeability. That is, it is made of a paper whose inside face is treated with a polyethylene. On the other hand, an outer bag 3 which houses a plurality of such small bags, for example, twenty small bags is formed without air permeability. That is, it is formed by using a sheet material wherein a polyester layer, a dry laminate layer, an aluminum deposit layer, a dry laminate layer, and a polyfilm layer are layered in sequence. In the outer bag 3, an oxygen scavenger 9 is put together with the small bag 1 and the bag 3 is sealed so as to obtain a packed article. In the packed article, the oxygen scavenger 9 acts also on the inside of the small bag 1, so that modification due to oxidation of the powdered foods in the small bag 1 can be prevented effectively.

Title: Semiconductor laser device
IPC: H01S5/16
Filed: 1992-03-19
Abstract: PURPOSE:To protect the end face of a semiconductor laser device against damage even when the device outputs laser rays of high power by a method wherein a surface level is restrained from being formed due to an oxide at the light emission end face. CONSTITUTION:A layer 51 of material which contains InP or InGaP is formed on the light emitting end face of a semiconductor laser device. As the lattice constant of the layer 51 is larger than the of an AlGaAs active layer 13, it is sharply enlarged in band gap a given compressive stress. Even surface level is a little generated on the surface of the layer 51, carriers trapped by the surface level concerned are injected again into the conduction band or the valence band of the AlGaAs active layer 13 through a tunneling effect and used for emitting light, so that the surface of the layer 51 is restrained from rising in temperature. That is, the layer 51 functions as a kind of a window layer. Therefore, the end face of an AlGaAs semiconductor laser device is hardly damaged.
